Hi,
From the office article
https://support.microsoft.com/en-us/kb/3054937#bookmark-prerequisite , after you apply this update, administrators have to run cmdlets by using SharePoint 2013 Management Shell to have the database upgrade take effect.
We must manually run PSCONFIG after Installing SharePoint Patches,
1. Open an Administrative command prompt.
2. Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\BIN
3. Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
For your reference:

Or you can run it from the Start >All program > Microsoft SharePoint 2013 Products > "SharePoint Products and Configuration Wizard.
